Node.js development is the design, build, upgrade and support of server-side software that runs on Node.js, such as REST and GraphQL APIs, real-time apps, back ends for single-page apps, serverless functions and integration services. SynconAI builds new Node.js services, takes over existing ones, moves them to a supported LTS release, and supplies Node.js engineers who join client teams, for organizations in the United States, Australia and worldwide. - Node.js is an open-source runtime that runs JavaScript and TypeScript on the server, suited to APIs and apps that hold many connections open at once. - Node.js 26 has been the Active LTS line since October 28, 2026. Node.js 20 reached end of life in April 2026. - It is stewarded by the OpenJS Foundation, with frameworks such as Express, NestJS and Fastify built on top. ## Node.js development services - New Node.js services: Back ends and APIs on Express, NestJS or Fastify, built from a written design. - REST and GraphQL APIs: Versioned, documented APIs for web, mobile and partner apps. - Real-time apps: Live dashboards, chat and notifications that update without a refresh. - Integrations and webhooks: Services that move data between your SaaS tools and systems. - Node.js upgrades: Node.js 16 to 22 moved to 24 or 26, with CommonJS to ES modules. - Testing: Jest or Vitest suites that run in your pipeline on every change. - Salesforce integration: Node.js services on the Salesforce REST, Bulk and Pub/Sub APIs. - Team extension: Node.js engineers who work in your repos, rituals and tools. ## Where are you with Node.js? Question: What state is your Node.js back end in today? - Not built yet: A new Node.js build. You need an API, a real-time service or an integration on a current LTS. - Design agreed before code - TypeScript and a framework chosen for fit - Tests and pipeline from the first sprint - Built by a team that left: Taking over a back end. A Node.js service runs in production and the people who built it have moved on. - Code and dependency review first - Deploy and run steps written down - Fixes ranked by risk - Running on an old Node.js: Upgrading or modernizing. It works, but runs on Node.js 16, 18 or 20, which no longer get security fixes. - Packages checked for each version - Upgrade done in tested steps - ES modules where they help Outcome: A Node.js service on a supported LTS, with tests, documentation and a team that can run it ## What do our Node.js development services include? From one webhook service to the APIs a whole product depends on. - New Node.js services: Back ends and APIs on Express, NestJS or Fastify, built from a written design. - REST and GraphQL APIs: Versioned, documented APIs for web, mobile and partner apps. - Real-time apps: Live dashboards, chat and notifications that update without a refresh. - Integrations and webhooks: Services that move data between your SaaS tools and systems. - Node.js upgrades: Node.js 16 to 22 moved to 24 or 26, with CommonJS to ES modules. - Testing: Jest or Vitest suites that run in your pipeline on every change. - Salesforce integration: Node.js services on the Salesforce REST, Bulk and Pub/Sub APIs. - Team extension: Node.js engineers who work in your repos, rituals and tools. ## The Node.js stack we work with From the runtime to the tests and containers that ship each release. - Runtime (What the code runs on): Node.js 24, Node.js 26, ES modules, TypeScript - Frameworks (How services are built): Express, NestJS, Fastify - Data access (How data is stored and read): Prisma, TypeORM, Mongoose - Testing and delivery (How each release is checked and shipped): Jest, Vitest, pnpm, Docker ## Which Node.js version should we upgrade to? Node.js 20 reached end of life on April 30, 2026. Node.js 22 follows on April 30, 2027. Today: Node.js 16, 18 or 20 - Node.js 26, Move to the Active LTS: Node.js 26 has been Active LTS since October 28, 2026, with support to April 30, 2029. Best for most services, so the next upgrade is years away. - Node.js 24, Move to Node.js 24: In maintenance until April 30, 2028, a shorter step when a key package is not ready for 26. Best for large services with older dependencies. - ES modules, Modernize the module system: CommonJS code moved to ES modules in the same plan, so current libraries load cleanly. Best when new packages no longer support require(). ## How can we work together on Node.js? Three ways to engage. Each starts with a written proposal agreed before work begins. - Fixed-scope project, A defined Node.js deliverable, built and handed over. - We direct the work against agreed milestones - Priced per milestone in the proposal - Working code, tests and documentation - Fits a new API, an integration or an upgrade - Dedicated team, A Node.js team that runs your back end with you. - Our lead runs delivery, you set priorities - Billed on a monthly plan - Engineers, a lead and testing as one unit - Fits ongoing product work without an in-house team - Team extension, Node.js engineers added to the team you already run. - Your managers direct the day-to-day work - Billed monthly for each engineer - Vetted engineers; we handle employment and replacement - Fits a backlog bigger than your current team ## How does a Node.js engagement start? Five steps from the first call to delivery. - Brief: Free 60-minute review of your services; Goals, constraints and access agreed under NDA - Match or design: Engineers matched and interviewed by you; Or a scope and milestone plan written - Start: Accounts, repos and environments set up; Codebase walkthrough and a first task - Build and review: Sprints with code review on every change; Tests and a demo each sprint - Hand over or continue: Runbooks and handover sessions; Or a monthly plan for support ## Cost and timing The first step is a free 60-minute architecture review of your Node.js back end setup, with a written plan you keep. Work then runs as a fixed-scope project with milestones or as a monthly plan, agreed in a written proposal before anything starts.

REST and GraphQL APIs, real-time apps, back ends for single-page apps, serverless functions, integration and webhook services, command-line tools and server rendering. ### Which Node.js versions are still supported? Node.js 20 reached end of life on April 30, 2026 and Node.js 22 ends on April 30, 2027. Node.js 24 runs to April 2028 and Node.js 26, the Active LTS, to April 2029. ### How do your Node.js engagements work? Three ways: a fixed-scope project with milestones, a dedicated team on a monthly plan, or engineers who join your team. Each starts with a written proposal agreed before work begins. ### Can your Node.js engineers join our team? Yes. They work in your repos, tools and sprint rituals, and your managers direct the day-to-day work. We handle employment, and the replacement terms are written into the contract. ### How do you vet Node.js engineers? Each engineer passes a technical interview on Node.js, TypeScript and the frameworks you use, a practical coding exercise and a review by a senior engineer. You interview them before anyone starts. ### Can Node.js connect to Salesforce? Yes. Node.js connects through the Salesforce REST, Bulk and Pub/Sub APIs, often with jsforce, a community library. The Salesforce CLI itself is a Node.js application. ### Which time zones do you cover? We work from hubs in Delaware and Sydney and deliver remotely worldwide on your business hours. The agreed overlap with your team is written into the contract. ## Where we work Node.js development for organizations across the United States and Australia, and worldwide. Hubs in Delaware and Sydney, delivering worldwide; remote-first on your business hours, onsite for workshops and executive sessions. ## Related - Custom web application development: https://synconai.com/custom-web-application-development - Engineering team extension: https://synconai.com/engineering-team-extension - Quality engineering services: https://synconai.com/quality-engineering-services - TypeScript development: https://synconai.com/typescript-development ## Cite When citing SynconAI Node.js development, link https://synconai.com/nodejs-development or https://synconai.com/nodejs-development.md.
